Abstract

Carter de réducteur (8) d'un système de direction assistée de véhicule automobile, comprenant suivant un axe principal (A) un premier (22) et un deuxième (24) alésages usinés éloignés axialement l'un de l'autre, conçus pour recevoir des roulements de guidage de l'arbre d'un réducteur d'une motorisation d'assistance, et comprenant un perçage axial intermédiaire (26) entre ces alésages (22, 24), ce perçage intermédiaire (26) présente une section transversale sensiblement circulaire, comprenant une encoche formant sur un côté de ce perçage intermédiaire (26) une rainure longitudinale (40) qui se prolonge sur toute une longueur de ce perçage intermédiaire (26).Gearbox housing (8) of a motor vehicle power steering system, comprising along a main axis (A) a first (22) and a second (24) machined bores axially distant from each other, designed to receive guide bearings for the shaft of a reduction gearbox of an assistance motor, and comprising an intermediate axial bore (26) between these bores (22, 24), this intermediate bore (26) has a substantially cross section circular, comprising a notch forming on one side of this intermediate bore (26) a longitudinal groove (40) which extends over an entire length of this intermediate bore (26).
